ROLLER-SKATE.

To all whom it may concern:

Beit known that I, EMERY EAs'rMAN HARDY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and yuseful Improvements in Roller-Skates, of which the following isa specification.

My` 'nventlon relates to improvements in roller skates, and ofv the type shown and described in the patents issued to me September 7, 1917, No. 1,228,111, and the object of my improvement-is simplicity and economy inconstruction and convenience and eliciency in use.

In the. accompanying V drawing Figure 1 is a side elevation of my improved roller skate. o Y Y..

Fig, 2 is an end elevation of the'same.

. Fig. 3 is a plan view of the same.

Fig. 4 is a bottom view o -f the same.

Fig.`5 is a similar view 'of the blank for the frame.

Fig. 46 is a similar view of the blank for the front heel plate. Y

Fig. 71is a similar view of the blank for one of the toe clamp members. d

Fig. 8 is Va-plan view vof a blank for a modification of lthe skate structure.

Fi .-9 is a side elevation of a skate having the rame made from theblank shown in Fig. 8, and having a single front wheel.

Fig. 10 is a similar view of the front part of a skate, having the frame made from the same blank, and having two front wheels.

Fig.. 11 is an end elevation of the skate shown in Fig. 10. Fig. 12 is a sectional view on 'the line laf-12 of Fig. 9. Fig, 13 is a sectional viewon the line 13 13 of Fig. 9. Y o

Fig 14 is a sectional view on the line 14.-14 of Fig. 10.

My improved roller-skate, as shown in Fig, 1, com risesva foot plate 10, supported at the rear y a pair of rear wheels 11 and f at the frontby a single, front wheel 12,

having at the rear end Va pair of back heel lugs 13 that are provided with a slot 14 for a sti-ep .and e suitable poetici faire@ 1915,- No. 1,152,813 and May 29,

specification of Letters Patent. Patented Aug. 20,1918.VV y Application mea June 27, 1917. Vserial No. 177,361. A 7

of the said rear end an` adjustable front heel lug 15, and provided at the front end with screw operated toe clamps 16 that are i combined `with front strap lugs 17, the latter having a slot 18 for a front or toe strap.v The front wheel 12 is positioned betweenv a pair of standards 19, and in the style 'l shown in Fig. l is constructed andheld in place after the manner shown in the patents mentioned, beingV mounted on a shaft 20 that is entered in a slot 21 in the standards and held in placeby a nut 22 in coperation. with awasher 23 and lugs 24 formed byy bending outwardly the lower end portions of the standards 19.

The; rear wheels 11 are supported,` by.

standards 25 that are in spaced relation, being` mounted on the outer endsv of a shaft 26, and for these wheels I'prefer to usev a special construction, to be described.-

The toe clamp 16 and toe strap lug'17 are part of a bracket member 27, there being two such bracket members 27, both being yoperated simultaneouslyl by the screw 28Y of,

the usual form.

AIn front of the front stardards`19, on'ieach' side, is a guide lug 29, provided with a slot 30, thatserves as a` guide for the bracketl v y 80 At the middle, just v,over the screw 28,.is A a 4downwardly projecting fin-like lug 31 member 27 that hasv a notch 32 that engages with the cylindrical, reduced middle portion33 of the screw 28, betweenothe two threaded por. tions 34, the latter being threaded one righ handedA and the other left handed.

The frontheel lug 15 which is part. ofa

said body portion 40, the vsaid body portion rear endka hole 41 having adjacent the said a@ at the front for the locking screw 3 6,

38- operating in Va longitudinal slot the-bearingl sleeves, is a washer 62 of sufi ficient diameter to engage with the inner,

with the standard 25.- .A n ut .64 engaged with the screw threaded end65 of the shaft 26 bears against the outer washer 62, the two nuts 64E serving to eect a rigid and positively held union or connection of the intermediate parts and to provide a bearing space between each pair of washers in which the.

wheel is free to turn.

The wheels 11 are formed of a pair of circular blanks of sheet metal, the hub portions 63 being turned inwardly to provide an opening to fit the bearing sleeve 61, and the peripheral portions being also turned inwardly to provide telescoping flanges, the outer flange 66 serving as the thread and the inner flange 67 being of sufficient depth, to eli'ect an operative lit within the outer, tread flange 66.

A similar' form of wheel structure may be used for the front end of the skate and adapted for use with the blank shown in Fig. 8. In this blank the front standards 19a are provided with holes 2la for the shaft in lieu of the slots 21.

In the style shown in Fig. 9 there is a single front wheel 12a mounted on av shaft 20a. In this structure the bearing sleeve 61a and the thrust bearing washers 62a are positioned between the standards 19a and the nuts 64a are on the outer sides thereof.

In the style shown in Fig. lO'there arev two front wheels 12b, making a four wheeled skate, the wheel structure except for size being precisely the same as for the rear wheel structure already described.

The special form of wheel construction described permits of securely tightening the nuts on the ends of the shaft, there being a positive backing extending continuously from the nut at one end to the nut at the other end, and independently of the wheels, so that such tightening does not affect the free running of the wheels.

The two part wheel described isl of simple form, adapted for'cheap construction.

The frame is formed without rivets or4 rigidly connected parts, all fixed parts being made integral by cutting and shaping the blank of sheet metal shown and devlugs'at the vrear end thereof, f clamping the said foot plate.

and arranged that the said locking screw operates indirectly to resiliently bind the said ing plate that serves to position the standardk appreciably inwardly from the edge portion of the foot plate.l l Y x 2. In a roller skate, afoot plate, rear heel 70 bracket guides on the lateral edges thereof, front wheel standards and rear wheel'st'andf` ards on the lower face thereof, the said footplate,` lugs, guides, and standards being-all integral partsof a unitary structure of sheet material and the said standards being connected byy means of positioning plates with 3. In aroller skate, a frame having a longitudinal slot, a front heel lug member supported by the said frame and having a body portion positioned on the upper face of the i said frame, adjacent the said slot, ahead po- Y sitioned on the under side of the said frame, v a neck passing through the said slot and connecting opposed edges of thel said body portion and head, a locking screw positioned in the said slot 'and in a hole in the said body portion, and the parts being so constructed opposed edges to the said frame and to directly clamp the said body portion generally to the said frame.

4. In a roller skate, a frame having a foot plate and a pair of clamping brackets slidably engaged with the said foot plate, clamping lugs extending upwardly and inwardly over the edges of the said foot-plate, slidably i to engage with the sole of a shoe, and a toe strap lug Valso provided vas a part of the structure of the said bracket.

5. Inra roller skate, a frame having a 1ongitudinal slot, a front heel plate positioned generally above the said frame, having at `10.5A

through the said slot and serving to hold the body portion of the saidplate to the said frame. y 6. In a roller skate, a pair of standards ,in spaced relation, a wheel positioned between the said standards, a shaft extending through the said wheel and also through each of the said standards and having clamping nuts at the ends, and a sleeve, concentric with the said shaft, serving as the Y bearing for the said wheel and as a spacer for the said standards.

7 In a roller skate, a pair of wheel standards in spaced relation, a shaft extending through the said standards, and a sleeve f1tting over the said shaft and also tting between the said standards, suitably to serve as a spacer for the said standards andas a bearingfor the said wheel. n

8. In a roller skate, a rearwheel structure comprising a pair of standards in spaced relation, a. shaft extending. through holdtheintermediate pants.l together, and. :i the-said standardgn spaoingsleeve mount.- ptirA of Wheelshoperatively mounte, on the 10 ed on the portion of the Said Shaftbetween saidbenring sleevegfan opertiielyhoused thesaidgstandards, a bearing sleeye mounted between theWash'erS attheends thereof.
